Erlang/OTP 24.2 is the second maintenance patch release for OTP 24, with mostly
bug fixes as well as a few improvements.
Below are some highlights of the release:
cryptoapp in OTP can now be compiled, linked and
used with the new
OpenSSL 3.0cryptolib. It has not yet been extensively tested,
so only recommended for experiments and alpha testing in this release.
There are not yet any guaranties that it works, not even together with other
OTP applications like for example SSL and SSH, although
there are no known errors.
erts: An option for enabling dirty scheduler specific
allocator instances has been introduced. By default
such allocator instances are disabled. For more
information see the documentation of the
erl_docgen, erts: All predefined types have been added to the
module together with documentation.
Any reference to a predefined type now links to that
documentation so that the user can view it.
erts: Responsiveness of processes executing on normal or low
priority could suffer due to code purging or literal
area removal on systems with a huge amount of
processes. This since during these operations all
processes on the system were scheduled for execution at
once. The new solution is to limit the number of outstanding
purge and copy requests to 2 times the number of schedulers as default
